The ligand prepared from PMBP with p-aminoacetophenone and its Cu(II), Co(II), Ni(II) and Zn(II) complexes have been synthesized and characterized by IR, UV, MS and 1H NMR spectra. The mechanism of thecondensed reaction has been discussed using quantum chemistry and molecular mechanics calculation, which can explain the enamine conformation of the ligand andthe imine-enol conformation of the complexes. The antibacterial activities have been screened for these compounds, among which the Co(II) and Cu(II) complexes have the most intense antibacterial activities.

Key words: PMBP-PAAP and complex, synthesis, structure characterization, mechanism analysis, antibacterial activity
